Correct Answer: C

Rationale: A sitz bath is an effective method for managing discomfort associated with an episiotomy after discharge. It helps reduce swelling and promotes healing in the perineal area. Ice packs (option D) are typically used immediately after delivery to provide pain relief. Promethazine (option A) and aspirin (option B) are not indicated for managing discomfort associated with an episiotomy. Promethazine is an antihistamine, and aspirin is a nonsteroidal anti-inflammatory drug, both of which are not commonly used for this purpose.

Correct Answer: C

Rationale: The client is experiencing compensated respiratory acidosis. The pH is within the normal range but is lower than 7.40, indicating acidity. The elevated CO2 level and low O2 level suggest respiratory involvement. The slightly elevated HCO3 level indicates a compensatory mechanism. In respiratory acidosis, the pH will be inversely related to the CO2 and bicarb levels, with elevated CO2 and HCO3 levels contributing to acidosis. Choices A, B, and D are incorrect because they do not align with the presented blood gas values and the compensatory response observed in this case.

Correct Answer: D

Rationale: The correct answer is D: Squeezing a ball. The first exercise that should be done by a client with a mastectomy is squeezing a ball. This helps in regaining strength and mobility in the affected area. Choices A, B, and C are incorrect as they are not typically the initial exercises recommended post-mastectomy. Walking the hand up the wall, sweeping the floor, and combing hair are activities that may be introduced later in the rehabilitation process.

Correct Answer: D

Rationale: Xerostomia is dry mouth, a common side effect in cancer patients. Providing a saliva substitute helps alleviate the discomfort associated with dry mouth by moistening the oral mucosa. Offering hard candy, as mentioned in choice A, can worsen xerostomia by increasing sugar content and potentially causing irritation. Administering analgesic medications, as in choice B, is not directly related to treating dry mouth. Splinting swollen joints, as in choice C, is irrelevant to xerostomia, which primarily affects the oral cavity.

Correct Answer: B

Rationale: A client with diabetes who has trouble seeing would require follow-up after discharge. The lack of visual acuity for the client preparing and injecting insulin might require help. Answers A, C, and D will not prevent the client from being able to care for himself and are incorrect. Living alone (Choice A) does not necessarily indicate a need for follow-up unless there are specific concerns. Having a cat at home (Choice C) and driving to the doctor (Choice D) are not direct indicators of the client's ability to care for himself.
